“…During 2007–2013, the phase arrows are less than 30°, indicating that the change of SPI3 leaded SRI1 for less than 1 month. That may be due to other factors interfering with the DPT (Han et al., 2019; S. Z. Huang et al., 2015). Although hydrological drought in subregion Ⅱ had no significant periodic characteristics, there was still a close relationship between meteorological drought and hydrologic drought at the time scale of 6–14 months (1981–1983), 10–16 months (1985–1987), 6–14 months (1988–1990), 6–16 months (1991–1994), 28–32 months (1994–1998), 20–28 months (2007–2012), and 16–20 months (2014–2017) (Figure 9b).…”

“…Previous studies have shown that drought could be closely related to precipitation, runoff, evapotranspiration, and soil moisture (Fang et al, 2020;Han et al, 2019). To explore the impacts of these factors on the DPT, this study calculated the multiyear mean values of the related meteorological and hydrological factors corresponding to different DPTs.…”

“…In addition, atmospheric circulation patterns such as the Arctic Oscillation (AO), the El Niño-Southern Oscillation (ENSO), and the Pacific Decadal Oscillation (PDO), and sunspots, are highly related to regional and local climates. They have been shown to affect global water vapor transport and redistribution (Huang et al 2017), and temperature fluctuations (Horton et al 2015), which thus affect local climate and vegetation growth (Cho et al 2014;Li et al 2015;Han et al 2019a). Dillon and Rundel (1990) studied the response of vegetation in the African desert in the 1982-1983 ENSO and found that vegetation dynamics was closely related to the event.…”

The long-term “Grain-to-Green Program” (GGP) on China’s Loess Plateau is a major global ecological engineering project which has significantly boosted vegetation renewal. Some studies have found that the rate of restoration is quite rapid during the implementation of ecological engineering, however, the influence of multi-scale climatic conditions on the performance of ecological engineering is unclear. In this study, multiple sources of remote sensing data were used to estimate the dynamics of vegetation structural and functional indicators, water-related local climatic factors, and atmospheric circulation factors. These datasets were also used to detect possible causes for vegetation restoration on the Loess Plateau over the past 20 years. The results show that widespread increases in rates of normalized difference vegetation indexes (NDVI), leaf area indexes (LAI), gross primary production (GPP), and aboveground biomass carbon (ABC) during 2000–2016 were significantly higher than before 2000. GPP was significantly correlated with rainfall and surface runoff on a monthly scale, and there were significant positive correlations between GPP and atmospheric circulation. Our results demonstrate that both vegetation structural and functional indicators rapidly increase, and ecological engineering greatly accelerated vegetation restoration after 2000. Local climatic conditions and atmospheric circulation patterns enhance vegetation growth and impact of ecological engineering.

Understanding and exploring hydrological (H) or soil moisture (SM) drought due to meteorological (M) drought under changing climate is crucial for drought early warning. Previously, different methods were used to calculate drought propagation from one state (M to another [H or SM]). However, each method has its pros and cons and thus cannot describe appropriate propagation attributes. In this study, a time series analysis is carried out to explore the propagation process in the Yellow River Basin (YRB) and Hai River Basin (HRB) of China. Standardized Streamflow Index (SSI), Standardized SM Index (SSMI), and Standardized Precipitation Index (SPI) 1‐month time series were calculated using streamflow, satellite‐based SM, and precipitation from 1979 to 2016. The time series framework identifies the average drought propagation as 3.4–8.3 months (M–H) and 2.3–5 months (M–SM) in YRB, while 2.8–7.7 months (M–H) and 2.3–8.5 months (M–SM) in HRB. Cross‐wavelet analysis indicated that periodic characteristics of M drought are responsible for these droughts. Overall, the findings of this study may help to minimize the drought hazards posed by M droughts.
